Abstract:

The entrainment flow field of a 7.1 cm toluene fire with a 51 cm floor has been recently studied using a laser Doppler velocimeter (LDV) and a particle imaging velocimeter (PIV). The results of these studies showed that the fire induced flow field in the presence of a floor is highly transient with root mean square (RMS) entrainment velocities having the same order of magnitude as the mean entrainment velocities.
